Great expression and well taken image. The watermark / logo is very distracting and detracts instead of adding to the image. If I was to split hairs and it was possible, I would have liked to see the loose hairs moved away from the models eye. I do like the decision to convert to mono, as it intensifies the mood and expression of the image.

When viewing this portrait full size, you really get the full impact. Beautiful lighting and I particularity like your subject's intense expression. The bokeh and shallow DoF adds a sense of dreaminess. A worthy feature Thilo! Well done!
